Lock for telescoping bags.



UNITED STATES PATENT EEICE.

LOCK FOR TELESCOPING BAGS.

SPECIFICATION forming part of Letters Patent No. 664,043, dated December 18, 1900.

Application filed April 16, 1900.' Serial No. 13.127. (No model.)

To all whom it may concern:

Be it known that we, CALVIN JAMES HOL- MAN and EBEEHAED GANeoLE, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Locks for Telescoping Bags, of which the following is a specification.

Our invention relates to animprovementin locks for telescoping bags, and has for its object to provide certain improvements in that character of lock wherein one member is carried by the body of the telescope or case and the other by the cover thereof and so constructed and arranged that when the cover is applied to the body of the telescope the two parts of the lock will be brought into operative engagement land may be temporarily secured or locked together, so as to prevent the cover from being removed from the telescope by an unauthorized person or accidentally in the handling of the telescope.

To this end the invention resides in the features of construction and the combinations and arrangements of parts hereinafter described, and particularly pointed out in the claims.

In order to enable our invention to be understood, we have illustrated the same in the accompanying drawings, wherein- Figure 1 is a perspective view of a telescopic case,showing our improved lock applied thereto. Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a transverse sectional view. Fig. 4 is a sectional view similar to Fig. 2, showing the key inserted in the lock and in engagement with the spring-bar. Fig. 5 is a perspective view illustrating details of the locking device, the lever being shown in a locked position. Fig. 6 is a similar view, the lever being shown in an unlocked position; and Fig. 7 is a perspective view of a key employed in connection with our lock.

Referring to the drawings, the numeral 1 indicates the body of the case, on each end of which is secured a vertically-disposed plate 2, having a series of teeth or projections 3 and provided on opposite sides with outstanding and laterally-projecting iianges 4. The plate 2 may be termed a ratchet-plate.

The numeral 5 indicates the cover of the case, on each end of which is secured a locking device designed to cooperate with the ratchet-plate 2. Each of these locking devices comprises a rectangular casing 6, which projects through a suitable opening in the end of the cover and is provided at opposite ends with ears or lugs 7, by means of which it may be secured to the material of the cover by means of suitable rivets passed through said ears or lugs and the cover, as will be understood. Along the sides of the casing 6, on the inside of the cover, are provided in wardly-extending iianges 8, which when the cover is placed upon the body of the telescope are designed to engage behind the flanges 4 of the ratchet-plate 2 and guide the cover in its sliding movement over the body and also prevent the end of the cover from beingpried outward to disengage the locking members7 as will be more clearly understood later on.

The numeral 9 indicates a j ournal-pin which is secured in the casing 6, near the bottom thereof, and upon which is pivotally mounted a lever 10, which is somewhat longer than the casing 6 and provided at its upper end with a suitable grasping device or handle 11. The outer side and top of the casing 6 are slotted, as .indicated by the numeral 12, to permit the lever l0 to be moved to a vertical position or to be pulled outward through the casing to unlock the two parts of the lock. On the lower end of the lever 10 and located above its point of pivotal connection with the journal 9 is an inwardly-extending projection or lug 13, which when the lever is placed upon the body of the telescope and the lever 10 is turned to a vertical position is designed to engage under a tooth of the ratchet-plate 2.

In order to provide for locking the lever 10 in an upright position, we provide the following mechanism: The numeral 14 indicates a spring-arm, which at its lower end is secured to the front of the casing 6, on the inner side thereof, and to one side of the slot 12 and eX- tends nearly to the top of said casing, where it is provided with a shoulder 15. Revolubly mounted in the casing 6, near its upper end and on the same side as the spring-bar 14, is a disk 16, to which is rigidly secured at its outer end a short locking-bar 17, which normally lies under and parallel with the springbar 14. The location of the disk 16 is slightly IOC above the shoulder 15 of the spring-bar 14, and extending through said disk and the locking-bar 17 is a triangular or other non-circular opening 18, in which is designed to be inserted the end of a key 19 having a similar configuration.

The operation is as follows: The cover being inserted upon the body of the telescope and pressed down as far as required, the lever l0 is then turned upward to a vertical position, whereby the lug 13 may engage beneath one of the teeth of the ratchet-plate 2. The end of the key 19 is then inserted in the opening 18 and turned so as to cause the lockingbar 17 to lie transversely of the easing 6, across the slot 12 and in front of the lever l0. When the locking-bar has been turned to a horizontal position, the shoulder 15 of the spring-bar 14 will spring beneath the under edge of the locking-bar 17, and thus hold it in a horizontal position. In this position of the parts the cover will he securely locked upon the body of the telescope, as the engagement of the two iianges l and 8 will prevent the cover from being pried outward to disengage the locking members, and the engagement ot' the lug 13 with the ratchet-plate will prevent the cover from being raised. To unlock the parts, the key 19 is inserted in the opening 18, where it will engage the upper end of the spring-bar 14. It is then pushed inward with some force in order to press the spring-bar inward and carry the shoulder 15 from beneath the under edge of the lockingbar 17. The key is then turned, and thereby the locking-bar is brought to a vertical position beneath and parallel with the spring-bar 14. The lever 10 may now he pulled outward through the slot 12,which movement will turn the lug 13 out of engagement with the ratchetplate, when the cover may be removed.

While we have herein shown and described our improved lock as applied to a telescopic case, it will be obvious that our invention is susceptible of other applications and to devices other than telescopes and especially to locking together any two parts which are brought together in sliding engagement.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is-

1. Alock for te1escopes,comprising aratchetplate secured on the body of the telescope, a locking device carried by the cover of the telescope and comprising a longitudinallyslotted casing havinga lever pivotally mounted therein and working in said slot, a lug carried by said lever and designed to be turned into and out of engagement with the teeth of said ratchet-plate, a locking-bar pivoted to said casing, and means for turning said locking-bar to cause it to lie transversely across said slot and in front of said lever to prevent the turning of the latter, substantially as described.

2. Alock fortelescopescomprisingaratchetplate secured on the body ot' the telescope, a lockingdeviee carried by the eoverof the telescope comprising a longitudinally-slotted casing, having a lever pivotally mounted therein and working through said slot, a lug carried by said lever and designed to be turned into and out of engagement with the teeth of said ratchet-plate, a spring-bar secured at one end within said casing and having a shoulder, a disk having a non-circular aperture, said disk being revolubly mounted in the casing above the shoulder of said spring-bar and having secured thereon a locking-bar normally lying beneath said spring-bar and parallel therewith, and a key designed to fit in said aperture whereby said locking-bar may be turned across the slot in the casing and in front of said lever and permit the shoulder of the spring-bar to engage beneath its under edge and to press said spring-bar inward to release its shoulder from engagement with the locking-bar and permit the same to be turned toits normal position, substantially as described.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
